A complete range of assemblies is available for PHOTONIS PMTs:• compact voltage dividers (VD family),• voltage divider and shield assemblies for very fast tubes (S563
family),• customised voltage dividers supplied attached to the tubes and
well adapted to large quantities (XA family),• photon sensing (XS family) or photon counting (XD family)
integrated modules including power supply (±12V) and more.
Though those products fulfill most user’s requirements, PHOTONIS also designs customised products.

1) A: iterative voltage divider which maximizes gain;
B: progressive voltage divider which optimizes linearity and in most cases the timing characteristics;
C: progressive voltage divider for certain fast tubes which provides a good compromise between A-type and B-type dividers for gain, linearity and timing characteristics.
2) The mentioned current is the anode current above which the linearity of the PMT is affected by more than 4%, due to the limitation of the divider circuitry; the PMT has however its own linearity, which is not included in this number; see Linearity and Voltage Dividers for more details.
3) at max. supply voltage.
4) -HV: cathode at -HV; anode grounded; +HV: anode at +HV, cathode grounded.
The VD200K, VD202K, and VD282K families are suitable for both +HV and -HV. They are supplied set for -HV operation. For +HV operation, remove the cap and modify the internal connections according to the instructions supplied with the base.
5) possible voltage adjustments with internal trimmer:
VD105K: G1 and G2 voltages; VD105K/01: G1 voltage; VD105K/02: G1 voltage; VD122K: D2 voltage; VD123K: G voltage; VD124K: G1 and D2 voltages; VD305K/B: G1 and G2 voltages;
6) The last 3 stages are transistorized, stabilizing the dynode voltages to within 1 V at up to 100 µA and above.

Voltage divider and shield for very fast tubesSpecial assemblies including a voltage divider and an optional mu-metal shield are available for 2” fast PMTs used to detect very brief low-intensity light pulses in physics experiments using coincidence measurements, Cherenkov light studies, high-speed scintillators, and in single photoelectron counting.
